Because I use TIR, I never used the default view key's.
The profiles just runs here on UP201 without any problems. (and 4.09m and AAA409b1)
Do you mean the view keys on HAT 1 does not work or are there other keys that does not work either?
I think it is not that difficult to get those working. Have to dig deep into my memory though, it is some time ago that I have run 201.
